Charlize Theron & Sean Penn: Trouble On Set

Charlize Theron is seriously butting heads with her boss…who also just happens to be her boyfriend, Sean Penn! The couple, who are currently filming The Last Face in Cape Town, South Africa, are learning the hard way that mixing business and pleasure doesn’t always work.

Sean is directing the film, while Charlize plays a lead role — and sources say she’s fed up with his constant criticism. “Sean is a different person on set,” an insider reveals. “He’s a perfectionist and it’s driving Charlize insane.”

In addition to interrupting the blonde beauty during her scenes, set sources say the actor also makes her do her lines over and over again and gets upset over her lack of passion. “Sean the director is not the man Charlize fel in love with,” the source adds. “They have been arguing big time.”
